Showing Hurricane Beryl forming along the South American coast and making landfall in Texas, USA through the Gulf of Mexico, this weekly 4K UHD color video is composed of thousands of NOAA day and night images of the continental United States and South America for July 1, 2024 through July 7, 2024. Synchronized with 8 North American satellite images per second and 4 South American satellite images per second, 40 minutes of real-time weather are viewed each second.
Credit goes to CIRA/NOAA for the GeoColor imagery.
GeoColor is a multispectral product composed of True Color (using a simulated green component) during daytime, and an Infrared product that uses bands 7 and 13 at night. During the day, the imagery looks approximately as it would when viewed with human eyes from space. At night, the blue colors represent liquid water clouds such as fog and stratus, while gray to white indicate higher ice clouds, and the city lights come from a static database derived from the VIIRS Day Night Band.
GeoColor was developed at the Cooperative Institute for Research in the Atmosphere (CIRA) and the STAR Regional and Mesoscale Meteorology Branch (RAMMB).
NOTE: Lighted areas shown in nighttime images are not real-time depictions of city lights. The layer is derived from a compilation of JPSS VIIRS Day Night Band images and is included for orientation purposes.
